Description
本發明係關於一種改良渦輪增壓器之方法，特別是一種關於主副葉片之增加渦輪增壓器操作域之方法。 The invention relates to a method for improving a turbocharger, in particular to a method for increasing the operating area of a turbocharger for main and auxiliary blades.
習知渦輪增壓器利用內燃機的排氣推動渦輪(turbine)來驅動整個渦輪增壓器的軸心轉動運作，軸心帶動壓縮器(compressor)來進行空氣壓縮，其用途是可以增加空氣的供應量進入內燃機或是鍋爐；在內燃機的應用中，最主要的功能是在於回收排氣中的能量來增加進氣，進而提升內燃機的性能與效率。現今的車輛透過渦輪增壓器的應用可以降低引擎的排氣量並且不損失內燃機的性能，進而提升內燃機的燃油消耗率與環保的訴求；此外，渦輪增壓器亦屬於高單價、高附加價值的汽車零組件；若以粗略方式估算，一顆裝載在具150馬力引擎上的渦輪，其平均單價約可達150歐元，目前全球汽車渦輪正以年增率10%的速度成長，年產量超過1,300萬件，年產值超過35億歐元，尤其以歐洲市場增加最為明顯。 The conventional turbocharger uses the exhaust of the internal combustion engine to drive the turbine to drive the entire turbocharger's shaft to rotate. The shaft drives the compressor to compress the air. Its purpose is to increase the air supply. Into the internal combustion engine or boiler; in the application of internal combustion engines, the most important function is to recover the energy in the exhaust gas to increase the intake air, thereby improving the performance and efficiency of the internal combustion engine. Today's vehicles can reduce the engine's exhaust volume through the application of turbochargers without losing the performance of the internal combustion engine, thereby improving the fuel consumption rate of the internal combustion engine and environmental protection requirements; in addition, turbochargers are also high unit price and high added value Automotive components; if estimated roughly, a turbine loaded on a 150-horsepower engine has an average unit price of approximately 150 euros. Currently, global automotive turbines are growing at an annual rate of 10%, with annual output exceeding 13 million pieces, with an annual output value of more than 3.5 billion euros, especially in the European market, the increase is most obvious.
渦輪段是將排氣能量進行轉換的重要零件，其 設計會牽涉到渦輪增壓器的運作範圍與性能，如果渦輪葉片不足，則渦輪增壓器有效增壓的轉速範圍會變高，進而產生所謂渦輪遲滯的問題，使得駕駛在操作車輛的過程中發生動力銜接有稍微躍動而不適的情況；相反地，如果葉片數量較多的渦輪增壓器沒有動力遲滯的問題，不過重量的增加是主要的缺點。 The turbine section is an important part to convert exhaust energy, its The design will involve the operating range and performance of the turbocharger. If the turbine blades are insufficient, the speed range of the turbocharger's effective supercharging will become higher, which will cause the so-called turbo lag problem, which makes the driver in the process of operating the vehicle. There is a situation where the power connection has a slight jump and is uncomfortable; on the contrary, if the turbocharger with a large number of blades does not have the problem of power lag, but the increase in weight is the main disadvantage.

以下係藉由特定的具體實例說明本發明之實施方式，熟悉此技藝之人士可由本說明書所揭示之內容輕易地了解本發明之優點及功效。 The following is a description of the embodiments of the present invention by specific specific examples. Those skilled in the art can easily understand the advantages and effects of the present invention from the contents disclosed in this specification.
請參閱第一圖，係為習知渦輪增壓器示意圖，如圖所示，一般的渦輪其葉片都是均等曲率及形狀，請參閱第二圖，係為本發明渦輪增壓器結構示意圖，本發明為達到減少渦輪裝置重量之目的，透過主要葉片的減少並且搭配副葉片來彌補渦輪的性能，使渦輪增壓器可以在高轉速下將廢氣的能量轉換成壓縮機的能量來提供足夠的壓縮空氣，且在低速也可以維持一定的輸出水準。 Please refer to the first figure, which is a schematic diagram of a conventional turbocharger. As shown in the figure, the blades of a general turbine are of uniform curvature and shape. Please refer to the second figure, which is a schematic diagram of the turbocharger of the present invention. In order to achieve the purpose of reducing the weight of the turbine device, the invention compensates for the performance of the turbine by reducing the main blades and matching the auxiliary blades, so that the turbocharger can convert the energy of the exhaust gas into the energy of the compressor at high speed to provide sufficient Compressed air, and can maintain a certain output level at low speed.
請參閱第三圖，係為本發明增加渦輪增壓器操作域之方法流程圖，本發明之增加渦輪增壓器操作域之方法，其步驟包含：S10提供一渦輪轉軸，該渦輪轉軸係為圓形柱狀結構；S20設置一渦輪轉體於該渦輪轉軸之周圍，且該渦輪轉體與該渦輪轉軸接合；S30設置複數主葉片於該渦輪轉體上，該主葉片係由渦輪 轉體之中央向外延伸；S40設置複數副葉片於該渦輪轉體上，該副葉片係由渦輪轉體之中央向外延伸；其中，該渦輪增壓器藉由減少複數主葉片數量使該渦輪增壓器高速下的轉速提升，該渦輪增壓器藉由增加複數副葉片使該渦輪增壓器低速下的維持其運作性能。 Please refer to the third figure, which is a flow chart of the method for increasing the operating area of the turbocharger of the present invention. The method for increasing the operating area of the turbocharger of the present invention includes the following steps: S10 provides a turbine shaft, and the turbine shaft is Circular columnar structure; S20 sets a turbine rotor around the turbine rotor shaft, and the turbine rotor is engaged with the turbine rotor shaft; S30 sets a plurality of main blades on the turbine rotor, the main blades are made by the turbine The center of the rotor extends outward; S40 sets a plurality of auxiliary blades on the turbine rotor, the auxiliary blades extend outward from the center of the turbine rotor; wherein, the turbocharger reduces the number of the main blades The speed of the turbocharger is increased at high speed. The turbocharger maintains its operating performance at low speed by adding a plurality of auxiliary blades.
藉此，本發明首先進行主葉片的減少，主葉片的減少可以有效解決渦輪重量的訴求，也可以增加高速下的性能，使得轉速可以獲得提升；為了彌補減少主葉片所造成渦輪增壓器遲滯的問題，因此以尺寸較小之副葉片進行彌補，使低速下的運作可以維持原來水準。 In this way, the present invention first reduces the main blades. The reduction of the main blades can effectively solve the turbine weight demand, and can also increase the performance at high speeds, so that the speed can be improved; in order to make up for the reduction of the turbocharger lag caused by the main blades Therefore, the auxiliary blades of smaller size are used to make up for the low-speed operation to maintain the original level.
高溫廢氣進入渦輪推動渦輪，渦輪旋轉後，廢氣會依序推動渦輪葉片產生旋轉與動力，當葉片數較少且在低速時，葉片所能提供的動力較少，因此要到特定速度後才能穩定進行氣體增壓，這個過程會產生渦輪遲滯的問題，但是當轉速提升後，其高速性能較優異；相反地，當葉片數較多而轉速在低速時，葉片所能提供的動力較綿密，因此所需要的特定速度較低即能穩定進行氣體增壓，但是當轉速提升至高轉速後，其高速性能會遇到瓶頸，因此首先進行主葉片的減少，主葉片的減少可以有效降低渦輪重量，為了克服葉片減少所造成的動力遲滯，因此輔以尺寸較小的副葉片；當轉速上升後，尺寸較小的副葉片效應減少，動力主要是以主 葉片來供應，因此不會有葉片多而造成高速域性能瓶頸的問題。 The high-temperature exhaust gas enters the turbine to drive the turbine. After the turbine rotates, the exhaust gas will sequentially push the turbine blades to generate rotation and power. When the number of blades is small and at low speed, the blades can provide less power, so they can only stabilize after a certain speed. The process of gas supercharging will cause the problem of turbo lag, but when the speed is increased, its high-speed performance is excellent; on the contrary, when the number of blades is large and the speed is low, the power provided by the blades is dense, so The specific speed required is low, which can stabilize the gas supercharging, but when the speed is increased to high speed, its high-speed performance will encounter bottlenecks, so first reduce the main blades. The reduction of the main blades can effectively reduce the weight of the turbine. Overcoming the power lag caused by the reduction of the blades, so it is supplemented by the auxiliary blades of smaller size; when the speed increases, the effect of the auxiliary blades of smaller size is reduced, the power is mainly based on the main The blades are supplied, so there will not be a problem of too many blades and causing performance bottlenecks in the high-speed domain.
